12/26/2007   Video: Melting glass in your microwave           more vids

Here's an alternate version of a classic physics demo. Rather than heating up a glass rod and then plugging it in to 120VAC, we heat up a glass bottle and plug it in to a few hundred watts of 2.1GHz RF.

A great idea for school science fair. Don't make a motor; everyone makes motors. MAKE A GENERATOR! Light a bulb.

 
  

ACCIDENTALLY PRODUCING X-RAYS
A note about x-rays and "plasma globes." When attaching light bulbs to a tabletop Tesla coil, some small bulbs fail to produce purple plasma streamers. The space inside remains dark, but the glass flickers blue, or white, or sometimes green. This shows that the bulb contains a fairly hard vacuum. If run at high voltages (above 10KV,) such a bulb will produce soft x-rays. USUALLY the x-ray intensity is insignificant. It's way too little to light up a fluorescent screen. Maybe you could take x-ray photos by exposing film for minutes or hours. It will certainly make a geiger counter click like mad, but only if your GM probe has a thin window (for alpha particles.). So, to avoid even the slightest x-ray hazard, use only those large 4-inch spherical bulbs for your "plasma globe." Stay away from small green-fluorescing aquarium bulbs! Here's some radiation info , you can compare canoe trips and peanut-butter toxins to x-ray risk.

ENOUGH OF VIDEOS!
How about some electrostatics? Try this:

- Connect a metal needle to a high voltage power supply. Connect a small metal plate to ground. Put a microamp meter in series with the plate's ground wire. (Ground the other power supply lead, of course.)

- Power up the HV and aim the needle at the metal plate from many inches distance. The microamp meter should indicate a large reading. "Electric Ion Wind" is flowing from the needle, to the plate, and through the meter to ground.

- Now blow some crosswind through the gap between the needle and the metal plate. This should deflect the "electric wind" and make the meter reading fall to zero, right? Instead, NOTHING HAPPENS. The microamperes reading remains the same.

- Uhhhh... OK now, maybe the ion flow is bending around to hit the grounded plate from the side. Following the e-field lines? So lets put a wide metal ring around the plate and connect it directly to ground (no meter.) If the electric wind gets deflected, it should miss the meter and flow directly into ground. Power up the needle, get some microamps on the meter, now blow some wind. AGAIN NOTHING HAPPENS! The microamp reading stays high. The ion path doesn't deflect!

- Really blast some wind across the path. Use a plastic straw, and hit the needle tip with some series crosswind. Nope, still the same. Maybe the microamps fluctuates just a bit, but essentially remains large. The ion paths won't move. They blast right through any crosswind I can throw at it.

- RATS! This means that I can't easily build an air-blast VandeGraaff generator using a HV supply, needles, and a small battery-powered fan. It also means I can't make a wind-speed sensor with no moving parts which measures the microamps difference between electric wind being received by two adjacent collector plates facing a single needle. A high-volt wind-direction indicator won't work; it just ignores the wind.

- SPECULATION: if the electric wind was made up of many slow ions, then even a gentle breeze would push it away from the receiving plate. Therefore, it must be composed of few/fast ions. It makes no sense! Ions should collide with neutral air molecules and experience large drag. Maybe the ion flow pattern self-organizes into very thin "filaments;" jets having narrow cores made of fast-moving ions. Thin filaments have a high RE (Reynolds Number), which allows them to move very fast but without turbulent breakdown. It's like the fast thin laminar stream of smoke above a cigarette. I wanted to make a hailstorm of ions, but instead I get a "death ray" beam far narrower than a human hair. Just like Tesla said.

- I lied about the videos. I made this one about gas-filled capacitors that magically pump themselves down to vacuum.

CURES YOUR ATHSMA TOO
Hey. IR GOGGLES FORCE YOUR LENSES TO FOCUS DIFFERENTLY! This means that the IR goggles (or simply some deep red goggles) would exercise your lens/muscles/brain system and force your lenses to excessivly stretch. (Or do they excessively contract?) Either way, this would be a form of "eye excercise" which might end your need for glasses. Sort of like wearing prism-glasses to correct the lazy-eye problem. For nearsightedness you'd want the deep colored (red? violet?) goggles. For farsightedness you'd want deep (violet? red?) goggles. Of course use polycarbonate or glass lenses to avoid any problems with UV damage.

INNER LIFE OF THE CELL
Years ago one of my early morning visions involved weird EM resonance forces between biomolecules at hundreds of nanometers distances. If my delusions were true, then there must be a huge hole in modern biology, a hole almost as large as the one which would remain if the physics of chemical bonding had never been discovered. Without the long-range frequency-keyed electromagnetic bonding force, all sorts of nanomechanical phenomena in cell machinery would remain entirely unexplained.

Now Harvard U. Media has a long animated movie of subcellular nanomachinery within leukocytes responding to tissue inflammation. Just as in my dream, all sorts of bizarre effects are unexplained: they're glossed over, or more frequently they're fudged by playing a motion sequence backwards (against the laws of thermo!) Specifically: HOW DO THE FRICKIN' ACTIN MOLECULES SELF-ASSEMBLE? The movie doesn't say. Instead they give us a picture of actin subunits magically pouring in from all directions and somehow finding the growing end. Uhhh... isn't that just an animation of depolymerisation and diffusion... but PLAYED BACKWARDS? Same with polymerization of tubulin: the subunits magically come running from great distances just so they can link up to the growing tubulin end. And these are just the most egregious examples. All through the movie there are molecules which somehow "know" where they're supposed to go, how they're supposed to rotate themselves, and they move with apparent intention over major distances. mRNA tips and ribosomes magically find the few rare membrane pores. Actin-snipping proteins both fly in from distances and also magically orient themselves through many degrees of freedom in order to bond to the fiber. Apparently the researchers are asking us to believe that all this happens by diffusion, by random tries and re-tries performed at high speeds. I got news for them: if you stick a padlock in a bag with a bunch of keys, you'll be shaking the bag a long time before one of the keys inserts itself. And in living systems, the bag should be filled mostly with quarters, with just a few keys, most of them not fitting that lock. And I thought *I* had delusions! But all this strange dishonesty will pop like a bubble if we admit the (possible) existence of a fairly simple thing: mechanical forces caused by AC electromagnetic fields in the nearfield regions between atoms and molecules having resonance lines at common frequencies. It's just attraction between electromagnets. But AC electromagnets. If their frequencies are different, they essentially don't recognize each other, and the net attraction becomes zero (well, it changes from attraction to AC vibration.) But if their frequencies are right ...or more likely a combination of different atomic frequencies in distant molecules are right ...then not only would the molecules pull together over relatively vast distances, but they would experience torques which twist them into proper positions. In other words, the unexplained "magically intelligent" motions of the macromolecules depicted in the above video might not be an exaggeration at all. They might be moved by electromechanical forces which act like simple computers communicating over hundreds of nanometers by coded radio signals.

 



  

KEELY SONIC SUPERHEATING WATER EXPLOSION CANNON!
One of the old postings on the "weird science" page involved a report where a column of water in an ultrasonic resonator flew upwards and punched a hole in the ceiling an in the roof above. See Keely ultrasonic explosion. While waiting at the opening of the "Steamboy" movie, several things suddenly fell into place for me. First, guess what happens if we leave some water for hours under high powered ultrasonic treatment? This degasses the water, removing all the dissolved air. Heating the water increases the effect. Second, what happens if we strongly heat some thoroughly-degassed water? If microbubbles are lacking, then the water temperature will rise far above 100C, and the water will be massively superheated. It may even superheat to such an extent that, once it starts boiling, the entire volume of water may convert to vapor. Finally, what happens if we place water in a resonant ultrasonic chamber where the transducer is located at the bottom? In that case the pressure excursions will be maximum at the surface of the transducer and at the surface of the water. But the upper water surface will cool by radiation, so if cavitation were to commence, it would be at the bottom of the water column against the transducer. All together, this is a recipe for a cannon, but a cannon where the bullet is a slug of water propelled by its own steam output. A tiny bubble will break out at the bottom of the water column, and the bubble will instantly fill with live steam. The water column will be smoothly accelerated upwards as the superheated water emits a downwards "exhaust" of hot water vapor. As the steam leaves the water, the water cools, but if the superheated temperature was high enough, the water would not stop cooling. As the water slug leaves the pipe, the vertical water surface will emit vapor in all directions with little propulsive effect, while the bottom surface will act like a rocket engine. But would this be enough to punch a hole in a ceiling? Well, we know that if a kilojoule capacitor discharge propels a water colunmn upwards, the water can punch a hole through a thick aluminum plate (tested by Richard Hull and Dr. Peter Graneau). Yet in this capacitor experiment, turbulent disruption converted their water column into a water spray after a few feet of travel through the air. But what happens when a superheated water slug sends steam outwards in all directions at high velocity? Maybe this would help preserve the shape of the water column on its journey towards the ceiling.

    Wagon-wheel reverse rotation effect
    During morning commute on I-90 I glanced at a truck wheel and noticed it had a pattern of light... which was rotating slowly backwards! It was the lug nuts. Obviously some garage mechanic had tightened the nuts to give a special pattern. As the six sides of the hex nuts flashed in the sunlight, the angle of each flash was slightly different as each of ten nuts moved past. It looked like a circular dotted line which moved opposite to the wheel's motion. I wonder how many mechanics know this trick? I wonder if the original inventor just had a weird mind, or do truck-repair depots tend to hire PhD physics types?

    To start, tighten all the lug nuts, then turn them so they all point at the hub. Now pick a nut as number zero and leave it as is. Go to nut number one, and if you have 10 nuts with 6 sides, tighten that nut by an extra 1/60th turn (ten times six to get a 60th.) Go to nut number two and tighten it by an extra 2/60ths. Repeat. When you get back to nut number zero, you still leave it alone (since you could also tighten it by 10/60ths or 1/6th turn, which would leave the hex facets still in the same relative position.) Now when the wheel rotates, the pattern of flashes will advance by 1/10th rotation when the wheel rotates once. But will the pattern turn backwards? Figure it out. It depends on which side of the vehicle you're adjusting. Maybe you were supposed to loosen each lug nut by 1/60th turn. Watch: video, 1.3 min, also newer video, 0.6 min

    Added note: these are somewhat common on the highway; more common than explained by over-educated garage mechanics. So, what happens if we align all the nuts parallel to a single line? This would happen if the nuts were tightened with a tire iron, and the angle of the handle was the same each time. This pattern gives annoying flashes, but it also gives a backwards-drifting pattern which is 6x slower than the wheel RPM. So it seems that these patterns are probably accidental.

    Energy-sucking atoms and molecules
    Remember energy-sucking antennas, where a longwave resonant coil can intercept radio waves even if they pass within hundreds of feet? And recall the speculations about odd forces hidden under the catch-all name "Van der Waal's", and what this might imply for biochemistry? Well, I finally encountered a mainstream physics article about just this topic. But it's not what I expected. Suppose you have an atom, a single highly-resonant atomic oscillator, on then end of a STM scanning probe. Suppose you bring it near another identical atom. Will there be some long-range forces which become strong when the two atoms are separated at less than a quarter wavelength? (E.g. if the atoms had a resonance line in the optical band at 500nM, then if placed within 125nM of each other would they strongly attract or repel?) The answer might be: NO. But INSTEAD, the atoms link together and refuse to change their separation! WEIRD! Resonant atoms trapped on adjacent surfaces create strong friction between those two surfaces, EVEN IF THE SURFACES AREN'T TOUCHING. In subcellular molecular machinery this could produce a "force" counter to diffusion, one which slowed any molecule which approached another with the same coded frequency. As with cockroaches and sowbugs who crawl more quickly when in a lighted region, the right kind of molecules would end up in the "slowed-down" regions under the fridge. You can find a bunch of articles about this AFM discovery via a Google search on "non-contact friction", also Google Scholar: noncontact friction and non-contact friction

     

      

    THOSE GOOGLE ADS
    I strongly resisted putting banner ads on AMASCI. They're all just ads for spammer products: diet pills and ringtones. They support unethical popup-ad companies. They insult our intelligence with "click the jumping monkey" animations. And as I found out with Network54, many banner ads are controlled by advertizers themselves, and they contain really nasty spyware and browser-hijackers. But Simon at scitoys suggested Google ads, and they avoid these problems. They're text-only and controlled by Google, not by shady advertizers. The company is non-evil (at least so far.) And more important, the ads "know" the page topic, so they usually put science-education ads on my site. You get ads for science fair products rather than for casinos. So, Quitcher Job, Live Off The Website Revenues? It actually looks possible. Would YOU become a big flaming sellout ...if it let you escape the nine to five world? :)

    A moon that fell?
    As a kid in the 1960s I remember staring at the world map in the classroom and *knowing* that the Americas fit with Europe and Africa like a jigsaw puzzle. In 1965 this was geological heresy, but the grade school kids like me were seeing something real, something that professional geologists denied. So now I'm looking at the map of Mars over my desk, and I know enough to take my first impressions seriously. The Valles Marineris is too straight. WAY too straight. Well, actually it's curved in a sine wave on the map which extends as a discoloration across more than half the planet. (World maps with sine waves drawn on them are plots of orbiting spacecraft, where the angled circular orbit is "unrolled" to form a wave.) Also, Valles Marineris is aligned with the Martian equator, so it's also aligned with the plane of the ecliptic where moon orbits lie. Also, Valles Marineris has many widely separate parallel features which are also perfectly straight. Also there are all kinds of crater chains parallel to the valley all around the same region. Yet explanations of this valley talk about a cracking crust. I don't believe it. There are linear gouges and discoloration way downstream from the main valley. I predict that within a few decades the expert opinion will shift: Valles Marineris is an astrobleme, it was carved out by a moon that fell from orbit. The Valles region doesn't extend all the way around the planet, so it probably wasn't caused by a planetary ring. Imagine the event! It's even more impressive than those craters left by direct asteroid strikes. An entire moon gradually hits the top of the atmosphere and starts heating up from gas compression. If it survives for several orbits, its heat output will bake everything below, perhaps turning continent-wide deserts into glass and leaving a scar so large that the professionals will miss it when looking right at it. Then it breaks up into two or three huge chunks plus lots of rubble, into a hundred asteroids, which then descend and roll across the land at orbital velocity from horizon to horizon like incandescent bowling balls the size of Manhattan. Downrange of the main strike the air is full of big dirt: flying boulders the size of large buildings which rain down and ...disturb the surface.

    Speed freak
    In his book "Surely You're Joking...", R. Feynman experimented with personal time sense, and he wondered what determines it. I think it might be social, not physiology. My first summer job was raking leaves on Elmira College campus, and it quickly became apparent that my normal rate of work was wrong. I did things much faster than the seasoned workers, and I attracted funny looks, so I adjusted my performance. I thought it was sort of stupid; why didn't everyone rake leaves normally instead of in slow motion? But slow raking was the "way you're supposed to do it," and anyone who strayed from the norm would encounter group pressure to slow down. But... that's how infants become people!!! We change behavior as we encounter immense nonverbal pressure from parents, friends, outsiders, etc., otherwise we'd all behave as one-year-olds even when adult. In different societies the standards are different; I've heard that tourists south of the border complain that everyone does everything slowly... and islanders complain about crazy Americans who are always rushing about. WHAT IF HUMAN TIME SENSE IS SOCIETALLY DETERMINED? I've experimented with this and find that it is. If I'm alone I can push myself to perform tasks much faster until until "faster" becomes habitual and unnoticed, but I get huge amounts of work done, and it takes forever for the clock to get to lunchtime. It feels like really waking up, at least until it starts being normal. Also, my usual body movements become tiring, and I find it's much easier to move in curves rather than starting/stopping the considerable mass of limbs. (Like switching to 'racewalk' rather than just speeding up my normal walk.) And when I tried it for days at a time, I started losing weight and had to eat extra meals. If I asked someone a question or tried conversing, their slow responses and slow thinking was quite irritating. But whenever I kept all this up in public, people responded badly. They seemed to be thinking "what's WRONG with that guy? What drug is HE on? Is he insane or something?" Bingo! That's the societal pressure which usually keeps its members living at the "proper" speed. It's the same as if I started acting like a 2-yr-old, or if I moved to a country where things happened at different speed: I'd encounter the same type of pressure to adapt. So... I wonder how far this can be pushed. Can we live at 5x normal? Will we get huge amounts of work done, then have a crash from "exhaustion of manic energy" or perhaps die prematurely of old age? Or go the other route and let the outer world speed up to 5x faster while we stay "the same."

     

    08/15/2005   More about nanobacteria in the biology section. (This is a fairly exciting controversy!) Suppose that when a bacterium splits in half, each half takes half the genome. If the two bacteria remained together, they could trade metabolic molecules and survive. Suppose they split into two, four, eight, etc. If this slowly happened over millenia, we could end up with species of bacteria smaller than viruses, where each cell isn't viable alone since they act as specialized organs of a colony. Wouldn't just such an evolutionary trick be the result of a deep underground nano-crevice environment and evolution pressure favoring smallness?  

      

    Random thoughts: if you pass a current through a bar magnet, it should create extremely instense circular fields inside. After all, the path surrounding the current is a closed loop of iron, and a low current should saturate the material. But wouldn't this path be disrupted if the current fell? The axial field of the permanent magnet would take over. Apply a weak AC to the bar magnet and create immense pulses of internal b-field. Are these detectable? Instead perhaps pass a cable through a narrow iron pipe to give the pipe internal circular flux patterns. Apply AC to the axial cable and look for pulses. Perhaps wrap a coil around the pipe to apply a bias.


    More randomness. In the Vasserfadden demo below, how thin could the water thread become? I should think that e-field forces would cause it to resist evaporation, as with electric ice needles. The water filament would be like an electret. But if the thread broke, would it contract to form a droplet, or would the e-field preserve its threadlike form? If it stayed threadlike, this means we could build a network, an aerogel, from nothing but water. The threads would be maintained by the strong e-field (unless closed loops of electrified water filaments are also stable, so the external field could be removed.) An electrically-stablized aerogel made from water vapor would possibly explain the observation of invisible wall phenomena.

    Don't miss SEATTLE WEIRD GENIUS REAL SCIENCE 2005, the 'science fair' in bldg #30 at Sand Point, Saturday July 16. I'll have a demo table there with microwave oven, Tesla coil, and bowl of argon gas.


    Remember Plasma Globes without vacuum? Getting ready for the above event; I executed some microwave oven mayhem at Wednesday's Seattle Outsider Artist Project: Dorkbot Mad Science night. New high voltage effects discovered! A microwave oven with nothing inside is a 2.5GHz high voltage source. A bag or balloon of pure Argon usually does nothing... unless you include a tiny fragment of carbon fiber. After the plasma outbreak, the glowing violet-white cloud will grow and grow, melting the bag, then crawling all around looking for every last scrap of argon left in the wilting glob of plastic. Argon inside a glass bowl was similar: when triggered by a speck of carbon fiber, it exploded into a radial burst of wiggling lightning. This was a first: it was normal-looking mini-lightning, but at 2.5GHz frequency! As soon as the argon heated up, the spark-brush turned into a bright fuzzy cloud which rose to the top of the bowl and melted holes in the plastic plate laying across the opening. With a bigger bowl we actually saw some spherical lightning: a small spark at the bottom of the bowl became a 2" glowing hemisphere which rapidly rose, becoming more and more spherical before being distrupted by the plastic plate.

    When you drop a dish, usually it bounces once. Then it shatters on the second bounce. After noticing this effect I started listening for it. Sure enough, in restaurants (etc.), when you hear a plate go "DONGGGGG" when it hits, it usually goes "smash/tinkle" during the second bounce. I FIGURED IT OUT! When the dish hits the first time, it bounces upwards, but it also starts wobbling fiercely. It rings like a bell, and the vibrating edges of the dish are probably moving at several hundred miles per hour. [NO THEY'RE NOT! It's like a spring, and the edge can only move as fast as the plate was moving when it struck. When it comes back down, the wobbling edge could hit at twice the plate's velocity at most.] Now "view the movie in slow motion." The edge of the dish is going in-out-in-out as the dish slowly falls towards the floor. When it arrives, the wobbling edge whacks the floor again and again and again... and it hits at such high speed that it seems like the dish fell from 100ft altitude [wrong, it will seem as if the plate fell from *twice* the altitude of the bounce], not the two feet it fell after the bounce. My conclusion: if you grab for a falling dish but you're not fast enough, don't give up. You have a good chance of either catching it after the first bounce ...or even just *touching* it briefly which will damp out the intense vibrations that usually make the dish explode on contact with the floor.

     

    06/21/2005   "Spirit Orb Photographs" made with water mist, dry ice frost clouds, fumed silica, etc. I find that a parallel grid of human hair w/separation around 0.5mm on camera lens will cast shadows, essentially drawing lines on each false ghost-orb. If your camera had a hexagonal iris, the "orbs" would all be little hexagons.  

      

    SHOOT PLASMA BOLTS FROM FINGERTIPS!
    This one was a brainstorm during Dorkbot Tesla Night at COCA gallery in Seattle. Get a tank of argon plus regulator, a glass vase or bowl, some hose, and an aquarium airstone. In a draft-free room, slowly fill the vase with cool dense argon. Argon is different than air or CO2: it supports immensely long electric sparks. Poke the end of your Violet Wand or Tesla coil into the argon pool and watch the huge flaming white streamers spew forth. Now for the next part. Ready? Place the HV electrode against the outside of the glass, then stick your hand inside. Blazing white plasma streamers spew from your fingertips! Feels like being poked by needles.

    WAVE-MOTION COLA

    Put some crushed ice in a translucent or transparent cup. Fill it half way with dark cola (the kind with sugar.) Then fill it the rest of the way with diet 7-up or diet lemonade (or even water.)

    The ice will distrupt the stream, keeping the two layers from mixing very much. You end up with dark cola at the bottom, and clear stuff at the top. (Sugar is denser.) If you tilt the cup back and forth, you can make slow-motion waves in the cola!

    Even if the pizza place doesn't have see-thru cups, you can still use the trick. First add ice, then fill half way with full-sugar drink, then fill it up with diet drink. This creates two layers. You can drink the diet Coke first, leaving the layer of non-diet Sprite for later. Just remember to add the diet drink second, and use a thick layer of ice to disrupt the stream.


     
      

    Idea for future hoaxes: leave messages on the cardboard tube inside toilet paper rolls. It's not so difficult to remove the tube if you bend it. Write a message, or even apply a professional looking sticker. Or perhaps carry around a rubber stamp made for just this purpose. "HELP, I AM BEING HELD PRISONER IN THIS SCOTT FACTORY." Or "HERE IS THE SECRET PHONE NUMBER, DO YOU DARE TO DIAL IT?" Put several copies on the same tube so it's hard to miss. Or even cause total amazement by wrapping a dollar bill around the thing. Reinstall the tube and put the roll back on the holder.

    The DC electric motor was invented by accident!
    Huh. I totally missed this fact in my schooling. Michael Faraday demonstrated the "motor" effect in the early years, but like Ben Franklin's electrostatic motors, it was only a lab curiousity. Volta's "pile" caused power supplies to become all the rage in science labs, and by the mid 1800s, several types of DC electric generators or "dynamos" were already in use as power supplies. So people were generating voltage with rotating coils and commutators. Then during an inventors' exhibition at Vienna in 1873, inventor Z. Gramme accidentally connected a steam-driven dynamo to a second similar unit, and to everyone's surprise the second one started spinning as a motor. Thus the modern multi-HP electric motor was "invented." We add the DC motor to the list of other accidental discoveries: Becquerel's radioactivity, Roentgen's x-rays, the Leyden capacitor, Oersted's electromagnets, etc.

    Ant trails at work. A narrow stream of black ants is flowing across my lab bench, up the side of a water bottle, into the squirt-tube and down inside. They're harvesting distilled water?!! The trail is coming from the floor, up the side of a box, across the top edge of some papers standing on edge, then up the voltmeter wires which happen to dangle over the edge of the tabletop. Following the trail backwards, I find that it goes about a HUNDRED AND TWENTY FEET back to the Mass Spectrometry lab at the end of the hall! It disappears under a fume hood. There must be several thousand ants in the trail. I guess the Chem. building ant nest must be hard up for water. I brush away ants and create a 3ft gap by cleaning away their scent trail with alcohol. But an hour later the gap has closed again. Ants trapped on the far side of the gap apparently find their way across.

    Playing with ant trails! I move the water bottle, but then the arriving ants start spreading all over the desk. So I give the ant colony a wet cookie (placed 120ft away near the origin of the trail.) If the ants are a signal in an optical fiber, then the cookie should act like an impedance mismatch; reflecting the outbound ants back to the nest. Sure enough, after an hour the ant stream decreases greatly. I brush the remaining ants onto the floor and disrupt their scent trail. But in the morning it has re-formed, this time traveling up to an old bottle of Moxie Cola with a tiny bit of dried syrup in the bottom. They're still using the edge of the papers in the box on the floor, this time crawling up another test lead, transferring to the power cable of the oscilloscope, then up to the shelf with the bottle. OK, this time I convert the entire "ant-flow optical fiber" into a Bragg mirror: I drip some sugar water at many places along the 120ft trail. Quickly the stream of ants at my end of the trail has dropped to zero.

    Hmmm: pranking possibilites. If I put a tiny bit of sugar water on a victim's desk, and also deposit a blob of ants, won't a few ants find their way back to the nest and create a new 120ft stream?

    Another brainstorm! It's crackpot physics time. Remember Pyramid Power? The original claim was that a cardboard pyramid could sharpen a disposable double-edge razor blade. While reading an " Uncle Al" physics note about laser ultra-black beam-dumps composed of stacks of hundreds of standard razors, suddenly several concepts aligned in my brain. First concept: Uncle Al notes that the blackness of the razor-stack can be compromised by knocking the arrayed razor edges against even a soft object. Second concept: by stropping an old-fashioned straight-razor, we do not sharpen it, instead we straighten the bent-over micro-edge of the hard steel. The very tip of the sharp edge becomes folded over with use, and abrading it on a soft surface will grab the edge and bent it straight. Third concept: What if Pyramid Power was genuine after all, but it was actually triggering some sort of memory-metal effect? Not sharpening the blade, but essentially it would spontaneously "strop" a razor blade? Fourth concept: shine a bright LED at a slightly damaged razor-stack beam-dump and use a photodiode to measure any slow changes in the return reflection. Spontaneous blade-straightening would now be measurable. Stick the thing in a pyramid overnight (perhaps with power turned off, if that has any effect.) See if you can detect any auto-stropping effects!

    A great mystery within microwave ovens: WHY DOES THE TURNTABLE SOMETIMES ROTATE BACKWARDS? I always wondered about this. The obvious explanation is that the turntable motor is a 60Hz synchronous induction motor. But why? Synchronous motors aren't as good as the normal kind. One thing might make sense: it forces your turntable to end up in the same position as it started. That way your coffee mug will be at the front, or the handles on the cassarole dish will be positioned correctly. But my microwave oven doesn't do this. Most of the time the mug ends up in a crazy position.

    Testing is required. I heated a mug of tea at work for a minute, and for the first time I actually watched the clock as the turntable rotated. AHA! IT ROTATES ONCE EVERY TEN SECONDS!!!! I verified the effect and it does work: as long as you punch in multiples of 10 seconds, your food will come back to its original position. But something's screwy. My oven at home doesn't do this, yet its turntable randomly starts off clockwise or CCW, so it must contain a synchro motor. So I timed the oven at home. Bingo: it rotates every 20 seconds. That explains everything. At home, if I punch in 30 seconds, or 10 seconds, then the turntable rotates an extra half turn, putting the soup bowl on the opposite side. Not to smart. How many people cook things for 20 seconds, or 40 seconds? A 3RPM turntable speed only works if you cook something for one minute. But now that I know about the problem, I can start only using multiples of 20 seconds.

    I'm playing with a UV keychain LED light. It's not very deep UV (400nM). More like violet. But it will make your teeth glow green, and your fillings are easy to see (I mean the white non-metal ones.) Fluorescing aqueous humor gives you some green pupils! I see little flecks of green all over my arm: fungus? Yep. The thick edges of my heel fluoresce green as well. Huh, what else are these things good for? They will light up the plastic strip inside $5 US dollar bills. They will charge up some ZnS "Glow In The Dark" plastic to very high phosphorescence. Ah, if you draw all over yourself with yellow-green Hi-lighter markers, the UV keychain flashlight makes the invisible lines light up brightly. Draw some finger bones.

      I stumbled across a new food. I feel like the discoverer of yogurt must have felt: disgusted, but not adverse to putting weird things in their mouth.

    I'd purchased some eggplants, and they were in the fridge for a couple of weeks along with some button mushrooms. When I finally got around to inspecting them, one was still OK, but the other one had a large brown spot several inches across. Strange, there was a mushroom stuck to the eggplant in the middle of the brown region. It was merged. The mushroom mycelia were still alive, and they were trying to absorb the eggplant! The brown region was somewhat soft, and when I tore the eggplant skin, the hole smelled like mushrooms. I returned the eggplantmushroom organism back to the fridge. A few days later I checked again and found that the entire eggplant had been assimilated. It was soft and mushroom-smelly within. Resistance was futile.

    Now I have to try sticking mushrooms against all sorts of different vegetables and see what results. Can mushrooms take over cold salmon? Since the storebought mushrooms are Agaricus Bisporus, we could call the process "Bis-porizing." I also need to try actually cooking one of these mutant beasts. Hmmm. What would happen if you fell into a coma while lying on a mushroom? You'd wake up all brown and mushroomy? With an unstoppable desire to hide inside a compost pile?

       Sometimes my subconscious delivers fully-formed visions in answer to questions from years ago. Today's vision: AC Kelvin water-drop generator. Half of a Kelvin electrostatic generator could be placed in the exhaust of a jet engine and produce megavolts at milliamps! There's more. I have a La Violette idea of military aircraft covered with Barium Titanate or perhaps PZT ceramic. How weird. Why PZT sheath? Ah, it's Jean Louis Naudin's "plasma sheet" idea where sonic booms can be eliminated by covering the airplane wings with a glow-discharge. But why use insulating ferroelectric? Well, I know that long dielectric filaments can act as "wires" for high frequency AC (the "right angle circuitry" idea.) If JL Naudin replaced his plastic covered hi-volt wires with PZT-encased wires, he'd still get purple plasma even if his operating frequency was greatly reduced. (Barium titanate acts almost like a metal conductor, as long as you use AC.) BINGO! Drive the Kelvin water-drop "inductor" electrode with slowly changing polarity, and your megavolts output will slowly change polarity also. With a jet engine driving it, how fast could this polarity change be made? Maybe raise it to a few hundred Hz? Without the PZT your metal aircraft would spew lightning bolts. But with the PZT layer, the whole thing would develop a sheet of plasma. It might even absorb radar pulses at the same time it modifies the transonic shock wave fluidics. Whew. It all hangs together and makes some kind of sense. I couldn't assemble the ideas piece-by-piece intentionally. They just pop up when I'm half dazed.  

    10/10/2004    Added Seeing Sound, an untested idea involving mirrors, strobes, and razor blades  

       A new traffic-wave phenomenon: the infinitely large traffic jam! I need to add this to Traffic Waves.

    The "infinite jam" occurs whenever a traffic wave stops moving backwards and instead becomes pinned to a certain point on the highway. It happens when each driver in the jam must sloooooowly crawl past the "pinning point" before accelerating freely again. A cop car by the roadside can cause this. So can a bridge crest or blind curve. In other words, the trailing edge of a traffic wave stops evaporating normally... yet its leading edge still grows as before, since more cars are piling on from behind. The region of solidly-packed traffic grows larger and larger with nothing to halt its growth. HOWEVER... if a single driver can pull the edge of the wave back away from the pinning point, then the wave begins moving again. The edge of the jam begins evaporating normally, and cars which pass the former pinning point have no reason to slow down (i.e. the "pinning" effect only occurs if a slow dense traffic-wave goes past.) Once un-pinned, the huge jam stops growing. It doesn't dissipate, but if it had yet to grow enormous, one driver can nip the gigantic traffic jam in the bud. It only takes one car to unplug one lane. In Seattle we have at least three of these continously-growing jams: the bridge crest on I-5 at the ship-canal bridge, and on 520 at the bridge crest just before the Lake Washington floating brige, and on I-5 North near the Senaca St. exit where cars exit into the express lanes. I've also seen these on 520 many times, where a cop has pulled someone over, causing a two-mile traffic jam to form (people won't roar off into the empty roadway if a cop is right there, so they drive many yards past before peeling out... so the wave remains pinned, and the backup grows enormous.)

       I was imagining crowds of people walking on city sidewalks, versus crowds driving on highways. The atmosphere is totally different. Our cars act as our masks, making us anonymous. (Well, some of us make tatoos with spraycans and stickers.) But while commuting, we're silenced and cannot talk (or even communicate) with everyone around us. Hmmm. Maybe I could build myself a voice? How about an ultra-powerful broadband comb-frequency FM transmitter which could override nearby car radios regardless of which station they're tuned to? Too much work. Brainstorm! Cellphones. An experiment for the daring: print out a large bumper-sticker on adhesive paper and stick it on the rear of your car. (Cover it with clear tape to waterproof the paper.) The sticker reads:
    DRIVER'S CELLPHONE
    425-222-4321
    (use your real cell number.) What will happen? Death threats from road-ragers? Random members of the opposite sex hitting on you? Do you dare to find out? It might actually be interesting, since all those thousands of drivers on the highway near you have absolutely no way to send messages to anyone around them... except to you.

    Idea for "Orbs" believers. "Orbs" are bright sphere- or disk-objects that show up when photographing cemetaries, haunted houses, etc. But many of these are simply the photoflash-illuminated dust motes or mist droplets hanging a few inches in front of the camera. The circular "orb shape" is a blurred image of a bright dot, and the shape is determined by the camera iris edge. If your camera iris is circular, the "orb" will appear as a disk, but if the iris is octagonal, the orb will look like an octagon. Ooo, idea! To settle the matter, place an opaque object on your camera lens! E.g. stick a thin slice of black electric tape across the lens. Or even make an "X shape" from thin tape slices. Now whenever you photograph a bright, small, blurred object such as a dust mote, the dark strips of tape will show up in the bright circular "orb image." On the other hand, if the "orb" is real, and is large and distant from the camera, you'll see no shadow-image of the opaque tape cutting across the "orb." Presto: any possible "orbs" can be instantly separated from the dust-mote images; the real orbs won't have a big fuzzy "X" across them. Also see some more ghost hunting suggestions.

    07/22/2004    Working on: What is laser "coherence? (VERY under construction)  
    I never really understood laser "coherence." While working on science museum exhibits, I found that books were full of mistaken explanations. Over the years I've noticed that even the advanced textbooks get it wrong. They talk as if laser coherence is caused by stimulated emission. Nope. The laser-medium amplifies light. But if you give it some incoherent light, it will only amplify it while preserving the incoherence. But then why do lasers emit coherent light? I finally figured it out. It's because the laser mirrors cause the laser to behave as a near-perfect "point source." As light bounces between the mirrors, any light which doesn't seem to come from a single tiny point will eventually wander away and be lost off the edge of the mirrors, while any light which DOES come from one tiny point will keep bouncing and be amplified. Get two parallel mirrors and look into the "infinite tunnel." Only light that comes from the distant "infinite" point will avoid crashing into the walls of the tunnel. (How many physicists or even laser researchers know that laser coherence is caused by the laser cavity? Textbooks teach that it's caused by individual atoms, by "in-phase emission!)

    We live in a free country? Well, I personally know two science people who've been raided in the last five years. One was invaded by the local cops because they decided that his home lab was a "crack lab." Another was raided by the FBI after they decided he was a child pornographer. They of course found nothing at all in either case. And in past years the state of California tried to make it illegal for individuals to own chemistry glassware. And now the guy below is hassled for having biology lab equipment at home. This crap is DANGEROUS. I'm not very political, but I know exactly who is the poster-child for the highly ignorant "dark forces" pouring fecal matter on the US constitution. I advise any science-hobby people in the USA to think very carefully about this trend before casting votes in the upcoming election. Consider writing your elected official.

    I just bought my own overhead projector. Apparently Boeing engineers are ditching all of theirs, so they're only $25 at Boeing Surplus warehouse in Seattle; (more for the fancy collapsible portable versions.) In the past at very small conferences I've had problems because they'll set up video for laptops, yet balk at tracking down an overhead. I've always wanted one of my own. Some evolution:

    2. Clay tablet (well, it does have "save." Lacks instant-erase)
    3. Napkin (for restaurants lacking dirt floors)
    4. Chalkboard (good for audiences above 5 members)
    5. Dry-erase whiteboard (less messy than chalk)
    6. Overhead projector (for huge audiences)
    7. Powerpoint (huh! wtf! CANNOT DRAW ANYTHING?!!! )
    Powerpoint: twenty thousand years of technical advancement has given us a "chalkboard" where nobody can draw sketches or schematics while thinking out loud, or while answering audience questions. Yet NOBODY NOTICED?!!! GAH!!!!! Powerpoint is a computer-based slide projector, and cannot replace overhead viewgraphs or even chalkboards. I shudder to think what the next stage could be. And I'm even more convinced that guys like "The Iceman" with their woven grass backpacks and wickedly sharp flint weaponry were the peak of advancement, while everything afterwards has been slow creeping unnoticed degradation. :)

       NEWS FLASH: Molten lava in your microwave oven!  I had a piece of 
       volcanic glass from a science store, so I perched it on the end of a 
       vertical metal cylinder placed in my microwave, heated it to a dull red 
       glow with a propane torch, then turned on the oven for several minutes.  
       A hotspot appeared on the obsidian, grew bright, then moved to the
       interior. After awhile the obsidian fragment glowed red again and the
       surface softened and cracked open, revealing a brightly glowing yellow
       interior which started flowing outwards.  Mini lava flow!  When cooled, 
       I found that the hottest part of the melted obsidian had foamed up and
       turned white.  Pumice!  Creating pumice in your kitchen from home-made 
       molten lava.  Apparently this obsidian is full of dissolved gasses, so
       it must have originally cooled while still underground (under pressure) 
       where it couldn't turn into pumice or into an ash cloud.  Note that I 
       only succeeded after removing the glass platter from the oven.  With no 
       other big absorbers in the oven, the platter was eating all the watts.
    
       OLDER: trying to melt pumice in a microwave oven.  It does glow
       orange when nuked (pre-heat with propane to trigger the effect.)  But 
       only the sharp edges soften.  Next to try: changing ash from Mt. St. 
       Helens back into lava again.
    
       EVEN OLDER: microwave ovens can melt glass, but only if the glass is 
       first pre-heated to dull red heat.  I melted a hole in the side of a 
       bottle by nuking it, after first heating up a small spot with a 
       plumber's torch.  I had to stop it after 60 seconds or the stream of 
       liquid glass might touch and shatter the rotating glass platter.
       The bottle shattered during cooling, so wear goggles!

       decorations.  You task is to release them from bondage.  Fly!  Be free!  
       But sitting against the ceiling is not freedom.  So, collect carrot 
       sticks and celery from the food trays, tie a hunk to each balloon, trim 
       down their strings to a minimum, then carefully nibble down the hanging
       vegetable until the balloon neither falls nor rises.  Leave it hanging 
       in air, and it will float annoyingly around on the air currents, or 
       perhaps be attracted to the back of various hair-dos by electrostatic 
       forces (especially if you've thoroughly rubbed the entire surfaces of 
       each balloon against your arm-hair before letting it loose.)  OK, Dr. 
       Von Fronk-en-steen, now combine several mylar balloons to make a single
       monster duct-tape zero-gee asteroid!  (See link below)
    
    10/22/2003  Added Antigrav Boulder.  Your pet asteroid drifts around the house.
    
       The Rijke tube" is a very strange device.  Jam some metal screen 
       into one end of a metal pipe, hold it vertically with the screen end
       downwards, and heat the screen with a flame.  The thing starts loudly 
       howling.  The gentle convection-breeze with the hot screen acts as an 
       audio amplifier.  The howl is feedback (a longer tube makes a lower 
       tone.)  Brainstorm: inject helium or CO2 into the lower end to change 
       the tone.  Send it a sequence of gasses and it will change your gas-data 
       stream into music.  Or be boring, and just add a telescoping pipe to 
       create a Thermal Trombone.
    
    09/30/2003  Added an Excel numerical toy, a pulse-wave crawling along a power line.
    
    
       Poor man's liquid nitrogen:  chunks of dry ice in an insulated
       container of rubbing alcohol.  Amazingly enough, many of the things you
       can do with liquid nitrogen are associated with its great thermal
       coupling power.  It's a liquid, so it touches the entire surface of any 
       object dipped within.  Dry ice is cold, and SEEMS to work poorly, so most
       people assume that this is because it's only -110F, not -320F.  Wrong.  
       It's because dry ice is not a liquid, and any object stuck into a dry 
       ice container is insulated by the layer of gas.  It cools down, but only 
       very slowly.  So, use dry ice chunks to chill some alcohol!  Then try 
       freezing and shattering a rose or a rubber band.  Make springs and chimes 
       out of solder or lead sheets.  Dip an operating LED into the stuff and 
       watch it grow intensely bright.  Some supermarkets carry dry ice (such
       as QFC in Seattle.)  Or check your yellow pages.  A buck a pound.
    
    09/22/03 Added a separate Comment Book to Electricity Questions page
    
        As a kid I tried to grow crystals using table salt.  But first I made
        a big jar of salt solution so the white stuff would settle out
        (salt is normally full of anti-caking agent.)   But then, my salt 
        solution ESCAPED!  It crawled out and made a run for freedom.  You
        see, salt grows crust, but the crust is wet with concentrated salt
        solution.  So then the crust grows crust.  And more crust grows on
        that.  Within a matter of hours your jar of salt solution can grow
        crust on the glass which extends up the side and over the lip, and 
        then the wet crust becomes a siphon.  If the humidity is low, the
        salt water crawls out and forms a large pool on the floor, leaving a 
        mysteriously empty jar.   Hey, maybe this explains how battery acid
        can escape from your car battery and form those big white crusty 
        things on the battery terminals.
    
    
    08/01/03  Always adding more to Weird Links, non-science
    
        People spend years learning to sound just like Jimmy Stewart or Elvis.  
        Why not do something far more useful: do impressions of YOURSELF, but
        a version of yourself who has a trachea full of Helium.  Make tapes of 
        yourself on helium, then learn to speak the same way but without any 
        helium.  Get several others together and go on the road... "Barbershop 
        Faux Helium Singers."  Maybe do some Mitch Miller numbers.
    
    07/22/03  Added PFI, a local Seattle legend, gourmet food warehouse store.
    
    07/18/03  Added Fingernails on blackboard, explained!
    
        Hey, that "threadlike electric wind" phenomenon from 1998 won the 
        Nobel prize last year.  Dr. J. Fenn uses it to make a row of micro droplets 
        each with protein molecules inside, then evaporates the water, leaving a 
        "beam" of charged proteins which can be accelerated in a vacuum chamber and 
        their mass determined.  "Electrospray ion-trap mass spectrometry."  The
        tiny droplets can travel at tens of MPH through the air apparently because 
        they behave like a moving column, not like individual droplets.  Nikola 
        Tesla wanted to use liquid mercury electrospray micro-droplets accelerated
        by a 100 Megavolt VandeGraaff machine.  He claimed that it was an effective
         weapon over many kilometers.  Like a water-jet cutter, but with a much 
        smaller and denser "blade."
    
    06/10/03  Adding more to How Transistors REALLY work.  Also a short version.
    
         If escalators are driven by standard AC motors, then as more and more
         people pile onto the descending escalator, finally the current phase 
         will reverse and energy will be dumped into the power grid.  The
         esclator's induction motor becomes a generator!   The escalator lowers 
         all those heavy flesh hunks, and the energy has to go somewhere.  If you 
         want to make a small donation to a company whose building has 
         escalators, then walk up the stairs, but ride the escalator down.
    
    06/05/03  Experimenting with cyborg text brain implants: the RSVP speed-reading
              protocol.  It's like text-to-speech software, but aimed at your
              retinas rather than ears.  Disable your eyes' muscles and pour the 
              text directly into your brain at high speed.  Here are three examples 
              done in GIF animation:  slow, fast, faster.
              See Speeder reader museum exhibit.
    
    06/04/03  Making The Ice which does not Melt
    
    05/24/03  At long last added an actual biology section.
    
    05/24/03  Added Human IR sense detects hail? to the 'weird sci.'
              section.  It's subjective and might not be real, so I didn't put
              it under 'amateur sci.'
    
          Sheep mowing your lawn?  Forget it!  You'd have to build a barn for 'em
          and clean up the sheep poop.  BRAINSTORM: plant your whole yard with
          catnip, and let the neighborhood cats keep it trimmed.   Actually 
          this might even work.  I noticed that at the end of winter my flowerpot 
          of catnip on the front porch wasn't regrowing, yet the stump had many
          tiny leaves.  I put a cage over it and within a day there were large
          green shoots taking off.  Neighborhood cats had kept it trimmed way back. 
    
    05/20/03  Added to misconception list: a Lemon Battery can't light a bulb.
              This classic school science experiment actually doesn't work.  It never 
              did.  Fortunately there are other things you can do with a lemon 
              battery. Also, if you have a supercapacitor, then you can cheat.
    
    04/18/03  Found old article:  making square wheels
              Anyone with some machine shop skills should try making a set of
              these things.  They look really cool when made in gleaming polished
              acrylic.  Stick them on a little axel and they'll roll smooth 
              and silently across a glass tabletop... yet they're CUBES.  The 
              tetrahedron version looks almost as odd.
    
         Where's the dividing line between "site update news" and "Blog"?  
         Have I injected sufficient humorous comments to qualify?
    
    
    03/30/03  Added OK, how do wings REALLY work to the Airfoil mistake section
    
    02/11/03  Updated hoaxes page with "Radioactive Nightmare"
              Also "megavolt body charger."   Make yourself into a human 
              VandeGraaff generator.  Use laying-on-of-hands to perform anti-
              healing ceremonies on cellphones and laptops.
    
    
           The word of the day is "Serrodyne."   I've heard of Heterodyne and 
           even Superheterodyne, but "Serrodyne" is a new one on me.  How could
           I have missed it?  Simple: it's very recent.  Also it's very 
           weird: change an incoming high-freq signal's frequency by using 
           Doppler shift!  Then just add your frequency-shifted signal to 
           the original, and then a nonlinear detector will give you a nice 
           low-freq signal at the difference frequency.  Hobbyists take note:
           it lets you treat a light signal as if it were a radio channel.
           Split any laser into several different frequencies, then put 
           separate data streams on each!
              
           For a microwave signal, just pipe it through a TWT (Travelling 
           Wave Tube) while constantly increasing the drive voltage on the 
           electron beam.  For a light signal, just constantly move one end 
           of an optical fiber (or instead wrap the fiber around a cylinder 
           of piezo material and then constantly increase the cylinder 
           diameter.)  This shifts the frequency by a constant value.  Mix 
           it with the original, shine it on a photodiode, and you've 
           moved a piece of the optical spectrum down into the radio 
           spectrum!   Pretty cool, eh?   Serrodyne lets you treat light
           as if it were radio frequency.
    
           Of course you can't keep up the constant change forever, and that's
           where the "Serro" part comes in.  Just move things in a sawtooth wave.
           Give your optical fiber constant drift in order to create doppler 
           shift, but every so often jump it back to the start.  Except for 
           those brief jumps, the signal frequency will end up shifted.  In 
           other words, you've created "Serrated heterodyne."
    
    02/07/03  Updated misconceptions list with why do clouds float?
              Clouds DON'T stay up there because the droplets are small, or
              because they're so light that existing updrafts can lift them.  
              They stay up there because the air inside the cloud is warm.
              Oh, and why is the sky blue?  Simple answer, but not one I've
              ever seen in any book.
    
    12/28/02  Added Drawing Holograms By Hand (2003), presented at SPIE Imaging conference.
              I actually submitted a paper to a science journal.  It's just
              a conference proceedings, but still.    Last thing I "published"
              was around 1980 as a coauthor on an instrumentation design for
              vision studies.
    
    09/03/02  Added IR filter-goggles, $10
              These really do work.  Greenery in the landscape looks very weird.
              They let you see right through certain types of black IR filter.
              Be careful though, it might not be wise to use them without good 
              solid UV protection.
    
    06/12/02  Added Dishonest Argument section to Closedminded Science
              During the next flamewar you can point out all your opponents'
              illegal ploys.  Or not.  "Never argue with an idiot.  They just
              drag you down to their level, then beat you with experience."

              During job-search I couldn't find a good Seattle jobs portal with
              all these company pages.  So I made a primitive one.
    
    05/07/02  Writing Ridiculed Discoverers, a list
              Aimed at those people who are certain that scientific concensus
              never makes mistakes, certain that crazy claims in science are 
              never proved valid in later decades.
    
    04/28/02  Added more to Skeptic Fallacies: They Laughed at the Wright Brothers
              Three very common arguments I constantly encounter in online 
              Skeptic forums.
    
    04/28/02  Found an old article of mine: Watts, Ohms, Volts, and Amps
              Two things flow in wires: charge and energy...  but they are 
              deeply interconnected via voltage and Ohm's law.
    
    04/23/02  Updated the High-voltage diodes and coil-winding page

    11/17/01  Merged the english text into  Grebennikov insect-antigrav book chapter
              Best crackpot article I've ever seen!  It has all the earmarks of 
              a genuine discovery.  That, or the guy spins a very believable 
              tale.  Biological nanostructures which harness undiscovered 
              elements of gravitational physics!  Since he kept the "antigrav" 
              insect species name secret, we'll never know if it was real.
    
    10/30/01  Fixed up weird newsgroups
    
    08/20/01  Added Brief testing of the Morton Effect
              I couldn't reproduce his claims.  But then later I realized that 
              my VDG machine has the wrong polarity.  I'll have to take it 
              apart someday and reverse the rollers.
    
    08/16/01  Update to carbon-to-iron experiment
              Alchemy!  heresy!  Striking an arc between big carbon blocks
              apparently creates a form of stainless steel, but without the
              usual problem of "radioactive grad students" or even 
              incandescent chickens.
    
    08/11/01  Added How do Transistors Work?
              No, how do they REALLY work.  What if we don't trust textbooks, 
              but instead figure out the physics from first principles?  This 
              is the "Babylonian" method espoused by Feynman (as opposed to 
              the Euclidian math-worshipping method used by contemporary 
              science.)
    
    08/09/01  Old article: "Bions, leukocytes, and floaters"
              Wilhelm Reich's "orgone energy" is partly based on a misperception;
              strange wigglers in the environment are actually inside your eye.
    
    07/05/01  Added GIF diagrams to Tesla's Greatest Mistake
              He used the Earth as a giant waveguide for 5KHz power transmission.

    03/20/01  Added a CUPPA BURNING PLASMA to  microwave demos
              Your microwave oven can create a pool of fluorescent gas.  Poke at it 
              quantum mechanically with salt grains.  It gets fiercely hot though, 
              and can shatter your Pyrex glassware.
    
    03/18/01  Added a graph of leakage for a small gravcap test (no thrust!)
    
    03/04/01  Added a couple of GIF drawings to INLINE KELVIN'S THUNDERSTORM
